I cannot reproduce this.  Does it happen only when you run Emacs via a
desktop shortcut, but not if you run it from the cmd prompt?

Do you have cursorType customized in the Registry, per chance?

I can tell you how to track the initial cursor drawing using GDB, but
if the problem only happens when Emacs is invoked from a desktop
shortcut, this could be a bit tricky.
